How about adding to k5crypto a krb5_crypto_init_keyblock,
with all the code from krb5_init_keyblock. Then change
krb5_init_keyblock to call krb5_crypto_init_keyblock.

Routines in k5crypto would always call the krb5_crypto_init_keyblock.
Other routines that continued to call krb5_init_keyblock would still
continue to work as expected.
